VDLATILE rite Manufacturing Company, Chicago, 111., a

corporation of Illinois Application September 10, 1932, Serial No. 632,504 19- Claims.. (01. 221-15) This invention has for its object to provide a receptacle for volatile liquids which is provided with a discharge nozzle or spout equipped with a normally closed sealing cap and with a carrying bail, and wherein the carrying bail also constitutes a lever which is so associated with the said sealing cap as to operate automatically to throw the latter to open. position as the receptacle is tilted to discharge position.

A further object of the invention is to provide a receptacle of the kind specified wherein the operating mechanism is very simple and. efiicicnt and is responsive to a shift in the position of the receptacle from its normal, upright position to discharge position when suspended to cause the discharge spout thereof to be opened.

A further object of the invention is to provide a receptacle for volatile liquids equipped as hereinabove defined wherein the. carrying bail and the sea-ling cap are so associated as to allow of. suflicient relative movement between the said parts to respond to normal swing of the receptacle body when suspended from said bail and while being carried from one point to. another to prevent the opening of the. said cap during this period.

A further object of vide a carrying bailof the type specified which, when released, falls to a positionfrom which it is not easily moved by accidental contact with other objects and from which it must be moved for an appreciably great distance before it can act to raise the cap of the spout.

A suitable embodiment of the invention is illustratedin the accompanying drawings, wherem:

Fig. 1 is a fragmentary plan view of a receptacle equipped with safety closure mechanism constructed in accordance with the invention;

Fig.2. is a vertical sectional view of these-me on the line 2--2 of Fig. 1.

Fig. 3 is a view similar to Fig. 2 showing-the receptacle and closure mechanism in discharge position.

Fig. 4 is a detail transverse line 4-4 of Fig. 1.

section on the Fig. 5 isa view similarto Fig. 2, showing a modified form of construction of the closurev mechanism.

As shown in Fig. 1, a casting having end portions 1 is secured to the head of the receptacle by means of rivets extending through said portions 1. The middle portion 2 of said casting spans the reinforcing ribs 3 formed in the head of. the receptacle.

the invention is to protongue 23 secured to stove-bolt 24 which The middle portion 2 of the said casting is equipped with a pair of parallel, upstandingarms 4 which border the vertical axis of the receptacle body. The carrying bail 5, including the gripmember 6 disposed at the top thereof, is equipped m with a pair of spaced apart parallel arms or projections 7 which are disposed between the arms 4 and are pivotally connected therewith by means of the pin 8.

The said carrying bail 5 consists, preferably, of a unitary casting or the like, the body portion of which extends angularly to the said arms '7 in order that the center of gravity of said bail may be dsposed out of alignment with and spaced appreciably from the vertical plane of the axis of the pin 8 so that. when said bail is released from the hand, as the receptacle is deposited, said bail 5 will fall by gravity to the position shown in Figs. 1 and 2.

Each of the arms '7 is equipped with a projection 9 and a cross-pin 10 is passed through said projections. and is also passed through the longitudinal slot 11 in a link 12 which is pivotally connected at its other end, with short arms of abellcrank lever 13 by means of the pivot pin 13 The bell-crank. lever 13 comprises a channeled sheet metal member having its middle or bottomv portion secured to the top of the closure cap 14 for the discharge spout 15 of the receptacle, the side flanges 16 of said bell-crank lever being ex- 35 tended outwardly from the cap 14 and said extended portions or arms being integral with the short arms to which said link 12 is secured; The said extended portions of the said side flanges 16 are pivotally secured to a bracket member 17 which is riveted to the spout 15 and which comprises a sheet metal stamping consisting of a middle portion through which the rivets 18 pass, the side flanges of said middle portion between which the said extended portions of the flanges 16 are received and towhich they are pivotally secured by means of the pin 19, and the side flanges 20' which rest upon the boss 21' of the receptacle head. It willb e noted that the side flanges of' the last-mentioned stamping are equipped with upwardly projecting portions or jears through which the pin 19 is passed.

The said cap 14 is maintained closed normally by means of. a helical-spring22 having a U-shaped the cap 14 by means of the also holds the gasket 25 in place, said spring being also equipped with terminal ends-26engaged with the middle portion of thestamping. 1'7, the main body of the spring *feature is advantageous in 22 comprising right and left helical portions through which the pivot pin 19 extends.

The said pivot pins 8, 13 and 19 are parallel with each other. The stamping ll opposes the middle portion 2 of the first-mentioned casting and also opposes the elbow portion of the carrying bail.

In Fig. 2, the normal positions of the several parts of the above-described mechanism are indicated in full lines and the position of the bail, when engaged for carrying the receptacle, is shown in dotted lines. It will be noted that this dotted line position is such that the cross-pin l0 still disposed at some distance from the rear end of the slot .11 of the link 12 so that the receptacle may swing quite freely relatively to the without causing the closure cap to be moved from its normal position.

The operation of the above-described mechanism is as follows:

After the receptacle has been carried to a point of discharge, the person carrying the same retains his hold on the bail with one hand and grasps the lower edge of the receptacle at a point diametricaily opposite the spout with his other hand and tilts the receptacle to discharge position as shown in Fig. 3. The weight of the receptacie causes the bail to be swung to the position, substantially, as shown in Fig. 3, thus causing the cross-pin 10 to draw the link 12 back and swing the closure cap to open position.

The particular advantage derived from this structure lies in the fact that it is not required that the operator shall set the receptacle upon the floor after having carried it to a point of discharge preparatory to engaging an operating le-- ver and then raising and tilting the same to discharge position, as is true of the receptacle of the same type most nearly resembling the receptacle of this invention with respect to gravity ope ion of the closure mechanism.

With respect to that type of safety receptacle wherein a spring-held lever is provided for control of the closure cap and which must be operated by the same hand as that which carries the receptacle, the advantage of the structure of the present invention lies in the avoidance of the extra effort required to operate the lever besides also obviating the necessity of depositing the receptacle in order to obtain a hold on said lever before tilting the receptacle to discharge position. 7

Another advantage of the structure lies in the fact that only one spring is provided for maintaining the said closure cap closed and that the carrying bail imposes its weight upon the link lZwhen the receptacle is not in use and thus adds to thenormal resistance to opening of the said can under the influence of internal pressure.

It will be noted that the end wall 2'7 of the slot 11 of the link 12 lying nearest to the closure cap, extends angularly to the longitudinal walls or the. said slot and that the cross-pin 10 bears upon said angular wall. The latter thus actsas a cam formation or shoulder against which the said cross pin l0 exerts a pressure which tends to move the link 12 longitudinally toward the closure cap 14 and thus exerts a pressure on the pin 13 to resist opening of said cap. This the event that the spring 22' should break.

In Fig. 5 I have illustrated a modified form of structure wherein the carrying bail 28 is devoid of the offset or elbow-portion of the bail of Figs. 1 to 4, inclusive, and is held normally in the poing bail, a discharge spout closure member for said spout, said bail having causing sition shown in Fig. 5 by means of the spring 29.

In all other respects the structure of Fig. 5 is substantially identical with that of Figs. 1 to 4, inclusive.

In order that the cap 14 may not be drawn back sufficiently far to break or set the spring 22, the carrying bail 5 is equipped with stop proiections so for engagement with the bridgemember 2 to limit the backward swing of said bail to the position shown in Fig. 3.

It will also be noted that the link 12 is engaged with the pin 8 when the bail is at the limit of its movement as shown in Fig. 3 to provide an additional means for so limiting its movement. Either or both said stop means may be employed;
